Densification of Sr-Mg doped SiAlONs with GPS and SPS
(Trans Tech Publications LTD, 2007)
At temperature above 1200 degrees C, the thermal stability of alpha-SiAlON phases has been debated since 1992; however, it has been discussed if any alpha-SiAlON phase can be formed in Ce, La, Eu and Sr-doped SiAlON systems. ...
Mechanical properties of alumina-mullite-zircon refractories
(Trans Tech Publications LTD, 2004)
The relationships between mechanical properties and microstructure of alumina-mullite-zircon refractories were investigated by varying zircon content. Various sintering temperatures were used for the slip-cast refractories ...
The corrosion resistance of alumina-mullite-zircon refractories in molten glass
(Trans Tech Publications LTD, 2004)
Corrosion measurements on a set of alumina-mullite-zircon refractories have been carried out using a static crucible test consisting of a "hole in a block". Rates of corrosion of the refractory at 1370 degreesC for 72 h ...
Effect of cathode slurry composition on the electrochemical properties of Li-ion batteries
(Electrochemical Society Inc., 2015)
The performance difference between commercial and laboratory scale cells remains a problem to be solved. Different way of battery electrode preparation is considered to be the main reason underlying various battery ...
Energy Harvesting Potential of Lead Free NBT-BZT Piezoelectric Ceramics
(IEEE, 2014)
In this study, Zr doped NBT-BZT (94Na(0.5)Bi(0.5)TiO(3)-6BaZr(x)T(1-x)O(3)) (x=0.1) powder was synthesis with solid-state method. The sintering process was carried out at between 1035 to 1180 degrees C in air for 2h. The ...
Energy Harvesting with Multilayer Piezoelectric Ceramics
(IEEE, 2014)
Energy harvesting from piezoelectric ceramic components can be achieved in three ways. These are impact induced, continues vibration induced, and decaying vibration induced. Defining the necessary characteristic of ...
Microstructural evolution R-?-SiAlON ceramics (R=Y, Y+Sm and Sm)
(2004)
Yttrium or samarium doped ?-SiAlON composition was sintered using gas pressure sintering through two different sintering procedures. One group of samples was heated up to 1800°C and then held for 1h while another group of ...
A Preliminary Study on Cell Wall Architecture of Titanium Foams
(Materials Research Soc, 2009)
Bio-inspired architectures, especially metallic foams, have been receiving an increasing interest for the last 10 years due to their unusual mechanical properties. Among commonly dealt foamed metals, like aluminum and ...
Chemical durability behaviour of bulk glasses in the Er-SiAlON system: Surface characterisation by SEM
(Trans Tech Publications LTD, 2004)
Er-SiAlON glasses were produced by melting appropriate powder mixtures under nitrogen at 1715 degreesC using a cation ratio composition of Er:Si:Al = 3.45:3:2 and with varying nitrogen contents (N= 5 to 22 equivalent %). ...
Investigation of parameters affecting formation of mullite from kaolin
(Trans Tech Publications LTD, 2004)
This study aims to improve the understanding of formation of mullite from kaolin at low process temperature using different sintering regimes. The optimum parameters affecting mullite formation from kaolin such as sintering ...
